here goes it: https://youtu.be/m41nYrDMHP8 it's not completely perfect yet, but in a good working state. Two chips might have been damaged in the process of building and testing it, i'm still investigating this matter. Yes, the audio is bad (mobile phone recording). but at least the button action sounds are audible :)

Well, that's been quite a bit of work, but finally, i've found and fixed this. It turns out (after checking really every slightest little other possibility) that the 10 MHz oscillator on this core was broken. I've changed it to a new one, as the last step before coming back here. Now all Cores are working and talking on MBNet! Thank you again for the support on this and while i'm here: a huge thank you in general to you, Thorsten, and the whole community here. There's so many amazing projects here and it's beautiful to see the development and all the new ideas after not visiting for a few years. Currently i'm working on the last issue i have with my handwired CS... this too was 'quite a bit of work' so far. I hope to get this last problem sorted out this week so i can start making music with the beauty! Although, right now i just remember that i haven't done a single audio test so far... i hope i don't run into bigger troubles again there :)

Thanks for you help, Thorsten! Indeed there was one shift register causing the cloning during reboot. I could identify it and change it to a new one. Problem solved for the moment and i can continue testing the CS. What still doesn't seem to work is cloning and/or uploading via MIDI to PIC 02, MIDI connection in general to this core seems to be an issue too (and the jumper in the right place of course). I guess it's possible that some incomplete uploading action has compromised the PIC in some way so i'll put this problem away and focus on the CS for the moment. I'll keep you updated and will share some pictures soon ;) Thanks again, Jakob

Hello Thorsten, thanks for your reply! Yes, the pic itself is working in the first socket and i'm able to upload the firmware. I have just confirmed that the problem still exists occurs the same way. Also i discovered that even if only a single pic is installed in socket U1_CORE1 it is trying to clone itself to other pics. Is this normal behaviour? Of course this fails (with a long wait period for each of the pics 01-03) with error message: Address: 0D !!!! By the way, at the moment i'm still working with only the mb-6582 base board, nothing attached except 5V supply, 8x 24LC512 and MIDI In/Out. No Pics installed, but all shift registers stuffed. Maybe this causes strange behaviour?

Hi all, I've been lurking around here on the forums for a while now. Some years ago i built my first MBSID v2, completely based on the modular mbhp. The device didn't last very long as i decided to do some modifications and then never finished the work. So poor little sid had to wait for some time, but now i'm back putting the system back together. this time with a mb6582 board. Now, this board is actually finished and tested and looks good and is supposedly working. But there's this one annoying problem i can't get rid of: i can upload to the first core (id 0) and it clones to the second core (id 1). After that it resets again and gets stuck for a while with this display output: Cloning Slave 02 Address: 0r Reset After this core 4 (id 3) gets cloned properly. Sadly, uploading the SID application to each core separately doesn't solve the situation. The problem stays and after every "cold" boot, the problem occurs again, sometimes even after the reset after core 3 got cloned. important to know: i'm working with an adapted setup_8580 at the moment, the control surface i (re)built is customized and a mix between mb6582 cs and old sid v2 cs. but that's another topic, first i have to get the thing to boot properly. I've also tried all the other .hex files, but they don't help either. Well, i've already spent way too much time on this, any input is appreciated, cheers, Jakob
